During an investigation into a fire, the team is confronted with racism, police violence and fake news.

Almost all of Alt-Bützenich is deserted and boarded up. At night a security service checks on everything. It was decided that the houses and the church would have to give way to open-cast mining. Then the climate change brings new hope: the old village can stay.

But the once close-knit village community has long since disappeared with the move to Neu-Bützenich. As Dr. When Christian Franzen, the local doctor, is informed that his empty house has been broken into, he immediately sets off - but never returns home. His wife Betje turns to the police, who find her husband - shot dead in the old village. Even though everyone here was a patient of the doctor, he was still not particularly popular. During their investigation, detectives Max Ballauf and Freddy Schenk uncover a torn community. Time cannot simply be turned back here in the lignite mining area.

In Bremerhaven, one of the largest automobile transshipment ports in Europe, a body is found at one of the car terminals - the driver area manager is lying dead in the trunk of a car.

The Bremen investigative team with Liv Moormann and Linda Selb begins the investigation and is supported by their Bremerhaven colleague Robert Petersen.

They come across Marie, Gheorghe Rusu and Oleg Rusu. The three car tuners secretly send cars along for night races and compete in spinning "doughnuts" when the car slides in circles with smoking tires. One of the vehicles turns out to be particularly explosive.

Liv Moormann quickly finds herself in the middle of the car tuning scene - and as a native of Bremerhaven, she not only meets forgotten friends, but is also confronted with her own family.

Chief Inspector Faber is back on duty, but his job as head of the homicide squad is gone for now. And prosecutor Matuschek wouldn't mind if nothing changed. Faber's colleague Rosa Herzog is now taking over the management on an acting basis. Chief Inspector Jan Pawlak, on the other hand, apparently has little interest in his job. Instead, he prefers to have fun in Alkim Celik's betting shop "Mutluluk" (Turkish for "luck").

When Celik's brother-in-law Lukas Becker is found dead, the "Mutluluk" suddenly becomes the focus of the investigation. An old acquaintance of Faber's is now back on the scene: Tarim Abakay . This time Faber doesn't want to let him get away with it. But his sleuthing doesn't remain without consequences for long: Faber is intercepted by Ira Klasnic and her two armed companions in the parking lot in front of his father's nursing home. Did Abakay send them?
